Key result
From 2011 to 2018, risk-adjusted in-hospital mortality rates remained stable for patients with STEMI (2.8% to 2.7%, P=0.46) but declined significantly for patients with NSTEMI (1.9% to 1.3%, P=0.0001).
Why the study?
To examine 10-year changes in patient characteristics, in-hospital treatment, and cardiovascular outcomes of acute myocardial infarction patients in the United States.
Population
604 936 STEMI and 933 755 NSTEMI patients at 1230 hospitals
Comparison
Annual trends from 2009 to 2018
Design
Registry-based retrospective cohort study
Follow-up
In-hospital
Loading...
Divergent MI mortality trends warrant subtype-specific surveillance; leaves open causal roles of therapies versus confounders in this observational analysis.
Observational (n=1,538,691)
Yes
Over a 10-year period in the US, acute MI patient risk factors changed modestly and treatment improved, with risk-adjusted in-hospital mortality remaining stable for STEMI and declining significantly for NSTEMI.
A 2022 study conducted an observational in Acute myocardial infarction (STEMI and NSTEMI) (n=1,538,691). Time period (2009-2018) vs. Earlier years within the cohort was evaluated on In-hospital risk-adjusted mortality rates (2011-2018). From 2011 to 2018, risk-adjusted in-hospital mortality rates remained stable for patients with STEMI (2.8% to 2.7%, P=0.46) but declined significantly for patients with NSTEMI (1.9% to 1.3%, P=0.0001).
